Prudential Jennison Growth & Income Fund
A Series of the Prudential Jennison Series Fund, Inc.

Performance At A Glance.

Led by large companies, stocks continued their record bull
market late in 1996
and into early 1997. In late March stocks began to falter as
the prospect of
rising interest rates and slowing corporate earnings growth
made many investors
wonder how long the market could continue to reach record
highs. During the
period, the Prudential Jennison Growth & Income Fund
produced returns which
were competitive with the average growth and income fund, as
measured by
Lipper Analytical Services.

Past performance is not indicative of future results.
Principal and investment
return will fluctuate so that an investorOs shares, when
redeemed, may be worth
more or less than their original cost.

Analytical Services.
The Fund charges a maximum front-end sales load of 5% for
Class A shares. Class
B shares are subject to a declining contingent deferred
sales charge (CDSC) of
5%, 4%, 3%, 2%, 1% and 1% for six years.  Class C shares
have a 1% CDSC for one
year. Class B shares will automatically convert to Class A
shares on a
quarterly basis after approximately seven years. Class Z
shares are not
subject to a sales charge or a distribution fee. No average
annual total
returns are shown because the Fund has been in operation for
less than one
year.

2Inception date: 11/7/96 for Class A, Class B, Class C and
Class Z shares.

3These are the average returns of 616 funds in the growth
and income category
since inception of the Fund, as determined by Lipper
Analytical Services.

How Investments Compared.
    (As of 3/31/97)
        (GRAPH)

Source: Lipper Analytical Services. Financial markets
change, so a mutual
fund's past performance should never be used to predict
future results. The
risks to each of the investments listed above are different
- -- we provide
12-month total returns for several Lipper mutual fund
categories to show you
that reaching for higher yields means tolerating more risk.
The greater the
risk, the larger the potential reward or loss. In addition,
we've included
historical 20-year average annual returns. These returns
assume the
reinvestment of dividends.

U.S. Growth Funds will fluctuate a great deal. Investors
have received higher
historical total returns from stocks than from most other
investments. Smaller
capitalization stocks offer greater potential for long-term
growth but may be
more volatile than larger capitalization stocks.

General Bond Funds provide more income than stock funds,
which can help smooth
out their total returns year by year. But their prices still
fluctuate
(sometimes significantly) and their returns have been
historically lower than
those of stock funds.

General Municipal Debt Funds invest in bonds issued by state
governments, state
agencies and/or municipalities. This investment provides
income that is usually
exempt from federal and state income taxes.

Taxable Money Market Funds attempt to preserve a constant
share value; they
don't fluctuate much in price but, historically, their
returns have been
generally among the lowest of the major investment
categories.

Portfolio
Manager's Report

The Prudential Jennison Growth & Income Fund invests
primarily in common stocks
of established companies with growth prospects believed to
be largely
unrecognized by the market. It is hoped that by combining a
focus on earnings
growth with a valuation discipline, the Fund can capture
strong total
investment returns. There can be no assurance that the Fund
will achieve its
investment objective.

Strategy Session.
- ------------------------------------------------------------
- -------------------
In selecting securities for your new Fund, we look for a
good earnings growth
outlook over the next two years in stocks that are also
selling at low
valuations when compared to the market. As a result, the
companies in the
portfolio are enjoying good earnings growth while their
stocks are selling at
prices relatively below those of the stocks of the market in
general.

The opening of your Fund last November coincided with the
U.S. stock market
setting all-time highs. At the same time, we also began to
see signs that
corporate earnings growth was slowing. Given such
conditions, we took our time
buying the initial stocks for your Fund. We were defensive
because we were
concerned that many stocks might be overpriced.

We believe this strategy of buying established companies
with strong growth
prospects at reasonable prices will benefit shareholders,
particularly at a
time when many are concerned about the high level of prices
in the stock market
in general.

Growth With Value.
We focus on earnings growth while we also look for companies
that we believe
are underappreciated by the market. For example, we have
significant
investments in the basic materials industry, believing that
these cyclically
sensitive industrial commodities are poised to participate
in worldwide growth.

What Went Well.
- ------------------------------------------------------------
- -------------------
We Had Some Winners.
Several of our stocks performed exceptionally well during
the period. We found
them in a variety of different industries, they had one
thing in common -- all
were experiencing strong corporate earnings growth.

- - Delta Airlines benefited from the recent boom in the
domestic airline
  industry, recently reporting earnings above Wall Street
expectations.

- - The New York Times continued to execute its operating
strategy well. Earnings
  received a boost from increased advertising lineage and
rates combined with
  reductions in newsprint costs.

- - CIGNA, the insurance and financial services company, also
exceeded earnings
  expectations. Its ongoing restructuring is on target, with
all sectors of the
  business on or ahead of plan.

And Great Expectations.
We have high hopes for the basic materials industry. The
global economy is
gaining strength, and we believe that some of the more
cyclically sensitive
industrial commodities are very well positioned to
participate in this growth.
So, we now hold a larger than market share in basic
materials, including such
com-panies as Reynolds Metals, Boise Cascade and Newmont
Mining.

And Not So Well.
- ------------------------------------------------------------
- -------------------
Not all earnings news has been good, however. Computer giant
IBM suffered
during the period due to investor nervousness about the
level of first quarter
earnings.

The energy sector, including our holdings in Anadarko
Petroleum, did not
perform as well as we had hoped in a period of falling
energy prices.

Despite these setbacks, we continue to hold these stocks
because we like their
prospects for growth.

Five Largest Holdings.

4.0%  CIGNA
      Insurance

3.2%  General Motors
      Automobiles and Trucks

2.6%  IBM

2.5%  Westinghouse
      Electrical Equipment

2.5%  Delta Airlines
      Airlines

Expressed as a percentage of total investments as of
3/31/97.

Looking Ahead.
- ------------------------------------------------------------
- -------------------
We are maintaining our relatively defensive posture because
of current
valuation concerns. We are pleased with the earnings growth
and valuation of
the portfolio and we will continue to invest
opportunistically in stocks of
established companies with good growth prospects and
attractive valuations.

President's Letter
May 14, 1997
- ------------------------------------------------------------

(PICTURE)

                         We're On Your Side

Dear Shareholder:

The past few months were mixed for most U.S. stock and bond
investors. The
recent news was good: The Dow Jones Industrial Average set
several record highs
in May and long-term interest rates were easing. The average
stock and bond
mutual fund finished the four-month period ending in April
in positive
territory. It was a different story only a few weeks earlier
when the Dow
declined significantly from another record high set in mid-
March, and long-term
interest rates were at the highest levels in six months.

The reasons behind these recent market swings have been
widely publicized --
higher interest rates and inflationary pressures. And while
we are watching
market developments closely, we are also very concerned
about you and how
you're dealing with events. We realize that staying the
course during times of
market uncertainty isn't easy. Here are some thoughts that
may help:

- - Keep Your Expectations Realistic. The best investors know
that financial
  markets rise and fall -- and so too, will the value of
their investments.
  Over time, however, stocks have been shown to produce very
attractive returns
  that were well ahead of inflation.

- - Remember Your Time Horizon. If your investment goals are
long term (several
  years or more), your time horizon should also be long
term. During this
  period, it's not unusual for stocks and bonds to
experience several periods
  of market uncertainty.

- - We're On Your Side. Your Prudential Securities Financial
Advisor or
  Prudential Registered Representative can help you
understand what's
  happening in the financial markets. They can assist you in
making informed
  decisions based upon a thorough knowledge of your
financial needs and
  long-term goals. Call him or her today.

Thank you for your continued confidence in Prudential mutual
funds. We'll do
everything we can to keep you informed and to earn your
trust.

Sincerely,

Brian M. Storms
President, Prudential Mutual Funds & Annuities

JENNISON GROWTH &
(Unaudited)                               INCOME FUND
- ------------------------------------------------------------
- -------------------
Prudential Jennison Growth & Income Fund (the 'Series') is a
separately managed
series of Prudential Jennison Series Fund, Inc., formerly
Prudential Jennison
Fund, Inc. (the 'Fund'). The Fund was incorporated in
Maryland on August 10,
1995 and is registered under the Investment Company Act of
1940 as a
diversified, open-end management investment company.
Investment operations
commenced on November 7, 1996.
The Series' investment objective is to achieve long-term
growth of capital and
income, with current income as a secondary objective. The
Series seeks to
achieve its objectives by investing primarily in common
stocks of established
companies with growth prospects believed to be
underappreciated by the market.
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting
policies followed by the
Series in the preparation of its financial statements.
Securities Valuation: Securities listed on a securities
exchange (other than
options on securities and indices) are valued at the last
sales price on the day
of valuation, or, if there was no sale on such day, at the
average of readily
available closing bid and asked prices on such day as
provided by a pricing
service. Securities that are actively traded in the over-the-
counter market,
including listed securities for which the primary market is
believed to be
over-the-counter, are valued by an independent pricing
service. Convertible debt
securities that are actively traded in the over-the-counter
market, including
listed securities for which the primary market is believed
to be
over-the-counter, are valued at the average of the most
recently quoted bid and
asked prices provided by a principle market maker or dealer.
Options on
securities and indices traded on an exchange are valued at
the average of the
most recently quoted bid and asked prices provided by the
respective exchange.
Futures contracts and options thereon are valued at the last
sales price as of
the close of business of the exchange. Securities for which
market quotations
are not readily available are valued at fair value as
determined in good faith
by or under the direction of the Board of Directors of the
Fund.
Short-term securities which mature in more than 60 days are
valued at current
market quotations. Short-term securities which mature in 60
days or less are
valued at amortized cost.
All securities are valued as of 4:15 p.m., New York time.
Securities Transactions and Net Investment Income:
Securities transactions are
recorded on the trade date. Realized gains or losses on
sales of securities are
calculated on the identified cost basis. Dividend income is
recorded on the
ex-dividend date; interest income is recorded on the accrual
basis. Expenses are
recorded on the accrual basis which may require the use of
certain estimates by
management.
Net investment income, other than distribution fees, and
realized and unrealized
gains or losses are allocated daily to each class of shares
based upon the
relative proportion of net assets of each class at the
beginning of the day.
Short Sales: The Series may sell a security it does not own
in anticipation of a
decline in the market value of that security (short sale).
When the Fund makes a
short sale, it must borrow the security sold short and
deliver it to the
broker-dealer through which it made the short sale as
collateral for its
obligation to deliver the security upon conclusion of the
sale. The Fund may
have to pay a fee to borrow the particular security and may
be obligated to pay
over any payments received on such borrowed securities. A
gain, limited to the
price at which the Fund sold the security short, or a loss,
unlimited in
magnitude, will be recognized upon the termination of a
short sale if the market
price at termination is less than or greater than,
respectively, the proceeds
originally received.
Dividends and Distributions: The Series expects to pay
dividends of net
investment income, if any, semi-annually and to make
distributions of any net
capital gains at least annually. Dividends and distributions
are recorded on the
ex-dividend date. Income distributions and capital gain
distributions are
determined in accordance with income tax regulations which
may differ from
generally accepted accounting principles.
Taxes: It is the Series' policy to meet the requirements of
the Internal Revenue
Code applicable to regulated investment companies and to
distribute all of its
taxable net income to its shareholders. Therefore, no
federal income tax
provision is required.
Withholding taxes on foreign dividends have been provided
for in accordance with
the Series' understanding of the applicable country's tax
rules and rates.

Note 2. Agreements
The Fund has a management agreement with Prudential
Investments Fund Management
LLC ('PIFM'). Pursuant to a subadvisory agreement

- -------------------
between PIFM and Jennison Associates Capital Corp.
('Jennison'), Jennison
furnishes investment advisory services in connection with
the management of the
Fund. Under the subadvisory agreement, Jennison, subject to
the supervision of
PIFM, is responsible for managing the assets of the Series
in accordance with
its investment objectives, and policies.
The management fee paid PIFM is computed daily and payable
monthly, at an annual
rate of .60 of 1% of the average daily net assets of the
Series. PIFM pays
Jennison a subadvisory fee at an annual rate of .30 of 1% of
the average daily
net assets of the Series up to and including $300 million
and .25 of 1% of such
assets in excess of $300 million. PIFM also pays the cost of
compensation of
officers and employees of the Fund, occupancy and certain
clerical and
bookkeeping costs of the Fund. The Fund bears all other
costs and expenses.
The Fund has a distribution agreement with Prudential
Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class
B, Class C and
Class Z shares of the Fund. The Fund compensates PSI for
distributing and
servicing the Fund's Class A, Class B and Class C shares,
pursuant to plans of
distribution, (the 'Class A, B and C Plans') regardless of
expenses actually
incurred by them. The distribution fees are accrued daily
and payable monthly.
No distribution or service fees are paid to PSI as
distributor of the Class Z
shares of the Fund.
Pursuant to the Class A, B and C Plans, the Fund compensates
PSI for
distribution-related activities at an annual rate of up to
 .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and C
shares, respectively.
With respect to the Class A Plan, PSI has agreed to limit
its
distribution-related costs to .25 of 1% of average daily net
assets for the
period ended March 31, 1997. With respect to the Class B and
Class C Plans, the
Fund compensates PSI for its distribution-related costs at
an annual rate of 1%
of the average daily net assets.
PSI has advised the Series that it has received
approximately $71,000 in
front-end sales charges resulting from sales of Class A
shares during the period
ended March 31, 1997. From these fees, PSI paid such sales
charges to affiliated
broker-dealers, which in turn paid commissions to
salespersons and incurred
other distribution costs.
PSI has advised the Series that for the period ended March
31, 1997, it received
approximately $35,000 and $600 in contingent deferred sales
charges imposed upon
certain redemptions by Class B and C shareholders,
respectively.
PIFM, Jennison and PSI are wholly-owned subsidiaries of The
Prudential Insurance
Company of America.
The Fund, along with other affiliated registered investment
companies (the
'Funds'), entered into a credit agreement (the 'Agreement')
on December 31, 1996
with an unaffiliated lender. The maximum commitment under
the Agreement is
$200,000,000. The Agreement expires on December 30, 1997.
Interest on any such
borrowings outstanding will be at market rates. The purpose
of the Agreement is
to serve as an alternative source of funding for capital
share redemptions. The
Fund has not borrowed any amounts pursuant to the Agreement
as of March 31,
1997. The Funds pay a commitment fee at an annual rate of
 .055 of 1% on the
unused portion of the credit facility. The commitment fee is
accrued and paid
quarterly on a pro-rata basis by the Funds.

Prudential Jennison Growth Fund
A Series of the Prudential Jennison Series Fund, Inc.

Performance At A Glance.
Stocks, led by the largest companies, surged to record highs
over the six
months ending in March. The stock market then began to slump
as the prospect
of rising interest rates and slowing corporate earnings made
many investors
edgy. The Prudential Jennison Growth Fund posted a small
gain during the
period, but did not perform as well as the average growth
fund, as measured by
Lipper Analytical Services. Our significant holdings in
midsized company
stocks hurt performance. However, we believe these stocks
will be very
attractive over the intermediate term.

Principal and investment
return will fluctuate so that an investor's shares, when
redeemed, may be worth
more or less than their original cost.

Analytical Services.
The cumulative total returns do not take into account sales
charges. The
average annual returns do take into account applicable sales
charges. The Fund
charges a maximum front-end sales load of 5% for Class A
shares and a declining
contingent deferred sales charge (CDSC) of 5%, 4%, 3%, 2%,
1% and 1% for six
years, for Class B shares. Class C shares have a 1% CDSC for
one year. Class B
shares will automatically convert to Class A shares on a
quarterly basis,
approximately seven years after purchase. Class Z shares are
not subject to a
sales charge or a distribution fee.

2Inception date: 11/2/95 for Class A, Class B and Class C
shares. On 9/20/96,
the Prudential Institutional Growth Stock Fund ("PIF")
merged into the
Prudential Jennison Growth Fund, Class Z shares. Performance
prior to 9/20/96
is for the PIF Growth Stock Fund, which had an inception
date of 11/5/92. The
inception date of the Prudential Jennison Growth Fund Class
Z shares was
4/15/96. The total return since inception (4/15/96) is 8.4%
with calendar
year-to-date total return through 3/31/97 of -2.1%.

3Lipper average returns are for 803 funds for six months,
738 funds for one
year, and 671 funds since inception of the Class A, Class B
and Class C shares
on 11/2/95.

change, so a mutual
fund's past performance should never be used to predict
future results. The
risks to each of the investments listed above are different
- -- we provide 12-
month total returns for several Lipper mutual fund
categories to show you that
reaching for higher yields means tolerating more risk. The
greater the risk,
the larger the potential reward or loss. In addition, we've
included
historical 20-year average annual returns. These returns
assume the
reinvestment of dividends.

U.S. Growth Funds will fluctuate a great deal. Investors
have received higher
historical total returns from stocks than from most other
invest-ments. Smaller
capitalization stocks offer greater potential for long-term
growth but may be
more volatile than larger capitalization stocks.

General Bond Funds provide more income than stock funds,
which can help smooth
out their total returns year by year. But their prices still
fluctuate
(sometimes significantly) and their returns have been
historically lower than
those of stock funds.

General Municipal Debt Funds invest in bonds issued by state
governments,
state agencies and/or municipalities. This investment
provides income that is
usually exempt from federal and state income taxes.

Taxable Money Market Funds attempt to preserve a constant
share value; they
don't fluctuate much in price but, historically, their
returns have been
generally among the lowest of the major investment
categories.

Portfolio
Managers'
Report

The Prudential Jennison Growth Fund invests primarily in
stocks of medium and
large companies (generally those with a total market value
of at least $1
billion) with above-average growth prospects. The Fund may
also invest in
stocks of foreign companies, investment grade bonds, and
securities issued or
backed by the U.S. government and its agencies, such as
mortgage backed
securities. There can be no assurance that the Fund will
reach its investment
objective.

Growth vs. Value.
There are two major schools of investing: growth and value.
Value investors
hunt for bargains -- companies that are fundamentally sound,
but whose stock
prices have declined due to a business problem or market
condition the investor
believes to be temporary. Growth investors, like us, buy
stocks of companies
that they believe have sales and earnings growing at a rate
higher than the
overall market.

Strategy Session.
Our strategy is to look for companies with above average
returns on equity and
assets, growth in sales and/or earnings or other fundamental
strengths. We
consider many factors, including the quality of management
and new products,
and whether a company's products or services fill a unique
need. We continue
to own stocks that we believe are cheap -- those selling at
low prices in
comparison with their expected earnings.

We continue to like medium- to large-company stocks with
solid earnings growth
potential over the next 12 to 18 months. This has led us to
increase holdings
in health care (particularly pharmaceuticals), financial
services, business
services (such as First Data and Reuters) and outsourcing,
among others.

In the consumer nondurables sector, we believe some stocks
have gotten ahead
of themselves in valuation, while others remain attractive
on improved
financials, such as Gillette and Disney. Consequently, we
have reduced our
exposure to this area.

We also slightly increased our technology holdings,
maintaining a larger
position in this sector than the broader market. We believe
the price declines
in this area were overdone earlier this year. Although
disappointing news for
some companies contributed to the decline of technology
stock prices in
general, we remain committed to these stocks.

Technology is the sector with the fastest earnings growth to
date in 1997, and
we expect a vigorous recovery. In fact, earnings performance
has come in
better than expected among our holdings.

What Went Well.

Technology Giveth ...
How volatile was technology? During the past six months,
seven of the
portfolio's top-performing stocks were in this sector. These
included a number
of top-performing companies with strong and improving
businesses, such as
semiconductor giant Intel, computer maker Dell, software
staple Microsoft,
magnetic disk drive maker Seagate Technology, and two
leaders in wireless
communication, Nokia and Ericsson.

We also saw some success in the drug industry. Strong
product pipelines and
improving profitability in pharmaceutical companies Eli
Lilly, Bristol Meyers
Squibb, Johnson & Johnson and Pfizer all helped the
portfolio during the
period. We did, however, eliminate our position in Johnson &
Johnson during
the period due to anticipation of slowing U.S. profit growth
next year.

Five Largest
Holdings.
3.2%         Intel
             Electronic Components
2.7%         Boeing
             Aerospace/Defense
2.6%         Disney
             Media
2.5%         Hewlett Packard
             Computer Systems
2.4%         Merck & Co.
             Pharmaceuticals

Expressed as a percentage of total investments as of
3/31/97.

And Not So Well.

 ... And Technology Taketh Away.
Conversely, five of the ten worst-performing stocks in the
portfolio were also
in technology. Notable poor performers included computer
communications firm
3Com, which is taking time to work through its recent
acquisition of US
Robotics. However, we believe in the long term this will
prove to be a
valuable deal for 3Com. Communications networking companies
Ascend
Communications and Cisco Systems also suffered during the
period, though we
continue to think each is well positioned.

Despite these setbacks in technology, we remain committed to
this volatile
sector, where we believe there is superior long-term growth
potential. A
stock's price performance is often based on short-term,
quarter-to-quarter
corporate profit expectations, a view so narrow that we
cannot allow it to
affect our longer term perspective in the Fund.

Looking Ahead.
We are cautious about the stock market's short-term
prospects. After seeing
nearly six years of consistently rising market levels,
investors may become
increasingly concerned about slower corporate earnings
growth and the Federal
Reserve Board's decision to increase short-term interest
rates.

In light of these situations, we believe the Fund is
positioned well. Our
portfolio is composed of the stocks of companies whose
earnings we expect to
grow on average more than 20% annually over the next year or
so. At the same
time, the portfolio is selling at an unusually low valuation
versus the
average of the market as a whole. Going forward, we believe
investors in
attractively valued companies, which deliver earnings
growth, will be rewarded
by the market. The Fund is positioned well to take advantage
of this potential

President's Letter
May 14, 1997
(PHOTO)
                          We're On Your Side
Dear Shareholder:
The past few months were mixed for most U.S. stock and bond
investors. The
recent news was good: The Dow Jones Industrial Average set
several record
highs in May and long-term interest rates were easing. The
average stock and
bond mutual fund finished the four-month period ending in
April in positive
territory. It was a different story only a few weeks earlier
when the Dow
declined significantly from another record high set in mid-
March, and long-
term interest rates were at the highest levels in six
months.

The reasons behind these recent market swings have been
widely publicized --
higher interest rates and inflationary pressures. And while
we are watching
market developments closely, we are also very concerned
about you and how
you're dealing with events. We realize that staying the
course during times
of market uncertainty isn't easy. Here are some thoughts
that may help:

- -  Keep Your Expectations Realistic. The best investors know
that financial
   markets rise and fall -- and so too, will the value of
their investments.
   Over time, however, stocks have been shown to produce
very attractive
   returns that were well ahead of inflation.

- -  Remember Your Time Horizon. If your investment goals are
long term (several
   years or more), your time horizon should also be long
term. During this
   period, it's not unusual for stocks and bonds to
experience several periods
   of market uncertainty.

- -  We're On Your Side. Your Prudential Securities Financial
Advisor or
   Prudential Registered Representative can help you
understand what's
   happening in the financial markets. They can assist you
in making informed
   decisions based upon a thorough knowledge of your
financial needs and long-
   term goals. Call him or her today.

Thank you for your continued confidence in Prudential mutual
funds. We'll do
everything we can to keep you informed and to earn your
trust.

Sincerely,

Brian M. Storms
President, Prudential Mutual Funds & Annuities

Notes to Financial Statements            PRUDENTIAL JENNISON
SERIES FUND, INC.
(Unaudited)                              PRUDENTIAL JENNISON
GROWTH FUND
- ------------------------------------------------------------
- --------------------
Prudential Jennison Growth Fund (the 'Series') is a
separately managed series of
Prudential Jennison Series Fund, Inc., formerly Prudential
Jennison Fund, Inc.
(the 'Fund'). The Fund was incorporated in Maryland on
August 10, 1995 and is
registered under the Investment Company Act of 1940 as a
diversified, open-end
management investment company. The Series had no significant
operations other
than the issuance of 3,334 shares of Class A and 3,333
shares of each Class B
and Class C common stock for $100,000 on September 13, 1995
to Prudential
Investments Fund Management LLC ('PIFM'). Investment
operations commenced on
November 2, 1995.

The Series' investment objective is to achieve long-term
growth of capital by
investing primarily in equity securities (common stock,
preferred stock and
securities convertible into common stock) of established
companies with
above-average growth prospects.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting
policies followed by the
Series in the preparation of its financial statements.

Security Valuation: Securities listed on a securities
exchange (other than
options on securities and indices) are valued at the last
sales price on the day
of valuation, or, if there was no sale on such day, at the
average of readily
available closing bid and asked prices on such day as
provided by a pricing
service. Securities that are actively traded in the over-the-
counter market,
including listed securities for which the primary market is
believed to be
over-the-counter, are valued by an independent pricing
service. Convertible debt
securities that are actively traded in the over-the-counter
market, including
listed securities for which the primary market is believed
to be
over-the-counter, are valued at the average of the most
recently quoted bid and
asked prices provided by a principle market maker or dealer.
Options on
securities and indices traded on an exchange are valued at
the average of the
most recently quoted bid and asked prices provided by the
respective exchange.
Futures contracts and options thereon are valued at the last
sales price as of
the close of business of the exchange. Securities for which
market quotations
are not readily available are valued at fair value as
determined in good faith
by or under the direction of the Board of Directors of the
Fund.

Short-term securities which mature in more than 60 days are
valued at current
market quotations. Short-term securities which mature in 60
days or less are
valued at amortized cost.

All securities are valued as of 4:15 p.m., New York time.

Securities Transactions and Net Investment Income:
Securities transactions are
recorded on the trade date. Realized gains or losses on
sales of securities are
calculated on the identified cost basis. Dividend income is
recorded on the
ex-dividend date; interest income is recorded on the accrual
basis. Expenses are
recorded on the accrual basis which may require the use of
certain estimates by
management.

Net investment income (loss), other than distribution fees,
and realized and
unrealized gains or losses are allocated daily to each class
of shares based
upon the relative proportion of net assets of each class at
the beginning of the
day.

Dividends and Distributions: The Series expects to pay
dividends of net
investment income, if any, semi-annually and to make
distributions of any net
capital gains at least annually. Dividends and distributions
are recorded on the
ex-dividend date. Income distributions and capital gain
distributions are
determined in accordance with income tax regulations which
may differ from
generally accepted accounting principles.

Taxes: It is the Series' policy to meet the requirements of
the Internal Revenue
Code applicable to regulated investment companies and to
distribute all of its
taxable net income to its shareholders. Therefore, no
federal income tax
provision is required.

Withholding taxes on foreign dividends have been provided
for in accordance with
the Series' understanding of the applicable country's tax
rules and rates.

Deferred Organization Expenses: Approximately $200,000 of
expenses were incurred
in connection with the organization of the Fund. These costs
have been deferred
and are being amortized ratably over a period of sixty
months from the date the
Series commenced investment operations.
- ------------------------------------------------------------
Note 2. Agreements

The Fund has a management agreement with Prudential
Investments Fund Management
LLC ('PIFM'). Pursuant to a subadvisory agreement between
PIFM and Jennison
Associates Capital Corp. ('Jennison'), Jennison furnishes
investment advisory
services in connection with the management of the Fund.
Under the subadvisory
agreement, Jennison, subject to the supervision of PIFM, is
responsible for
managing the assets of the Series in accordance with its
investment objectives
and policies.

The management fee paid PIFM will be computed daily and
payable monthly, at an
annual rate of .60 of 1% of the average daily net assets of
the Series. PIFM
pays Jennison a subadvisory fee at an annual rate of .30

of 1% of the average daily net assets of the Series up to
and including $300
million and .25 of 1% of such assets in excess of $300
million. PIFM also pays
the cost of compensation of officers and employees of the
Fund, occupancy and
certain clerical and bookkeeping costs of the Fund. The Fund
bears all other
costs and expenses.

The Fund has a distribution agreement with Prudential
Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class
B, Class C and
Class Z shares. The Fund compensates PSI for distributing
and servicing the
Fund's Class A, Class B and Class C shares, pursuant to
plans of distribution,
(the 'Class A, B and C Plans'), regardless of expenses
actually incurred by PSI.
The distribution fees are accrued daily and payable monthly.
No distribution or
service fees are paid to PSI as distributor of the Class Z
shares of the Fund.

Pursuant to the Class A, B and C Plans, the Fund compensates
PSI for
distribution-related activities at an annual rate of up to
 .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and C
shares, respectively.
With respect to the Class A Plan, PSI has agreed to limit
its
distribution-related costs to .25 of 1% of average daily net
assets for the six
months ended March 31, 1997. With respect to the Class B and
Class C Plans, the
Fund compensates PSI for its distribution-related costs at
an annual rate of 1%
of the average daily net assets.

PSI has advised the Series that it has received
approximately $222,000 in
front-end sales charges resulting from sales of Class A
shares during the six
months ended March 31, 1997. From these fees, PSI paid such
sales charges to
affiliated broker-dealers, which in turn paid commissions to
salespersons and
incurred other distribution costs.

PSI has advised the Series that for the six months ended
March 31, 1997, it
received approximately $349,200 and $3,700 in contingent
deferred sales charges
imposed upon certain redemptions by Class B and C
shareholders, respectively.

PIFM, Jennison and PSI are indirect, wholly-owned
subsidiaries of The Prudential
Insurance Company of America.

The Fund, along with other affiliated registered investment
companies (the
'Funds'), entered into a credit agreement (the 'Agreement')
on December 31, 1996
with an unaffiliated lender. The maximum commitment under
the Agreement is
$220,000,000. The Agreement expires on December 30, 1997.
Interest on any such
borrowings outstanding will be at market rates. The purpose
of the Agreement is
to serve as an alternative source of funding for capital
share redemptions. The
Fund has not borrowed any amounts pursuant to the Agreement
as of March 31,
1997. The Funds pay a commitment fee at an annual rate of
 .055 of 1% on the
unused portion of the credit facility. The commitment fee is
accrued and paid
quarterly on a pro-rata basis by the Funds.
- ------------------------------------------------------------
Note 3. Other Transactions with Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly-owned
subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months
ended March 31, 1997,
the Fund incurred fees of approximately $561,000 for the
services of PMFS. As of
March 31, 1997, approximately $102,000 of such fees were due
to PMFS. Transfer
agent fees and expenses in the Statement of Operations
include certain
out-of-pocket expenses paid to non-affiliates. For the six
months ended March
31, 1997, PSI earned approximately $13,700 in brokerage
commissions from
portfolio transactions executed on behalf of the Fund.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than
short-term investments,
for the six months ended March 31, 1997 were $299,397,926
and $252,265,431,
respectively.

The cost of investments for federal income tax purposes at
March 31, 1997, was
$676,579,610 and, accordingly, net unrealized appreciation
of investments for
federal income tax purposes was $92,486,848 (gross
unrealized
appreciation--$120,278,587; gross unrealized depreciation--
$27,791,739).

The Fund will elect to treat net capital losses of
approximately $6,706,000
incurred in the eleven month period ended September 30, 1996
as having been
incurred in the current year.
- ------------------------------------------------------------
Note 5. Capital

The Fund offers Class A, Class B, Class C and Class Z
shares. Class A shares are
sold with a front-end sales charge of up to 5%. Class B
shares are sold with a
contingent deferred sales charge which declines from 5% to
zero depending on the
period of time the shares are held. Class B shares
automatically convert to
Class A shares on a quarterly basis approximately seven
years after purchase. A
special exchange privilege is also available for
shareholders who qualified to
purchase Class A shares at net asset value. Class C shares
are sold with a
contingent deferred sales charge of 1% during the first
year. Class Z shares are
not subject to any sales or redemption charge and are
offered for sale to
specific categories of investors.
